How To Choose The Right Crimping Machine

How To Choose The Right Crimping Machine More than 95% of current crimping machines provide power sources using hydraulic systems, which are occasionally used in low-pressure hose crimping machines or sanitary hose crimping machines that use pneumatic systems or levers to provide power. The oil pump of the hydraulic system is equivalent to the human heart, and its role is very important. Choosing gear pumps as the power source of the crimping machine often considers its low cost, cost-saving, and low requirements for oil cleanliness, but its shortcomings To provide a lower pressure, which is only equivalent to 60% of the pressure of the plunger pump. It is noisy and has a short lifespan. Due to the lower supply pressure, manufacturers often consider sacrificing the expansion and contraction capacity of the crimping machine in order to increase the crimping force. Improve the conversion of axial force and radial force of the crimping machine, so it is often possible to choose a gear pump crimping machine when the customer's requirements are not high. Using plunger pump as the power source of the crimping machine has the advantages of providing high pressure (300kg/cm2), long pump life, low noise, such as YCY series can automatically variable fuel supply, low pressure large flow, high pressure small flow, the same specifications The motor saves 30% of electricity and the hose that is crimped is not easy to leak oil. Because the system is high, it can be designed to achieve a larger opening under the same crimping pressure, so that customers can use it for a long time. But its disadvantages are: higher cost, the same displacement pump, the plunger pump is 8-10 times that of the gear pump, which increases the cost of a single machine, and requires relatively high oil cleanliness, but considering the basic performance Input-output ratio, choosing YCY system variable pump crimping machine will be very cost-effective.

Is there a limit to the crimping hose diameter of the crimping machine?

Is there a limit to the crimping hose diameter of the crimping machine? The crimping machine is an important auxiliary machine of the hose braiding machine, which is used in general hose production. It can effectively solve the problem of hose fitting sealing. The working principle of the crimping machine is to use high-strength liquid pressure to physically deform the connecting part of the hose fitting, so that the metal sleeve on the outside of the hose and the inner tube core are tightly combined, so as to achieve the function of sealing and leakproofing. Each crimping machine has restrictions on the diameter of the crimping pipe and the size of the nut. Generally speaking, the hose diameter suitable for the crimping machine is below 10cm. For the hose above 10cm, the crimping type hose connection is generally no longer used. Most of them are connected by hoop. Withholding range, the conventional is 6-51mm, withholding hose diameter 6-51mm spot supply is exported to the country's largest sales of 1.5 inch hose crimping machine, 2 inch hose crimping machine. Suitable for all kinds of mechanical high and low pressure oil pipes, air hoses, water hoses, cable joints, automobile air conditioning hoses, automobile power steering hoses, oil hoses, gasoline supply hoses, as well as construction accessories, daily hot water hoses, widely used in vehicles, High-pressure tubing presses, high-pressure tubing presses, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. When the user is crimping the high-pressure hose, if the crimping amount is too small, and the pressure between the joint and the hose is too loose, the crimping hose may come out of the joint at the beginning of use under the action of oil pressure. If the crimping amount is too large, then If the joint and the hose are pressed too tightly, it is easy to cause local damage to the inner layer of the hose, causing cracks. The hydraulic oil will directly enter the steel wire layer from the rupture, and then leak out along the gap between the steel wires to the end of the outer jacket, or continue along the steel wire layer. It accumulates somewhere, causing the outer layer of glue to bulge or even break. When crimping, the crimping speed should not be too fast, which will easily cause damage to the inner rubber and breakage of the steel wire layer, which will damage the hose prematurely during use. In actual work, when replacing the high-pressure hose, the length of the selected hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the degree of bending of the hose should be minimized. Most of the damage of the high-pressure hose is caused by improper production. .

Matters Needing Attention In Daily Use Of Crimping Machine

Matters needing attention in daily use of crimping machine The use of crimping machines has been very common and extensive. There are certain operating procedures in the process of use. The crimping machine manufacturers need operators to be familiar with the entire related production process, and to be particularly familiar with the entire operating process of the crimping machine. Let's take a look at what are the operating steps and precautions during use? 1. When using the tube press for the first time, it should be crimped 20 to 30 times without load, and it can be used after observing that all parts of the ferrule pre-installation machine are normal. 2. When using the pipe press in winter, it should be withheld for 20 to 30 times without load to increase the oil temperature. 3. Press the open button, after the mold base is opened, select the corresponding mold to install on the mold base according to the specifications of the hose to be crimped, and adjust the micrometer scale (see the crimping parameter table for details). 4. Place the rubber tube with the joint in the proper position of the tube press, so that the entire length is crimped at one time. 5. Press the crimping button to execute crimping operation until the crimping head stops crimping and automatically opens the mold. 6. Take out the crimped hose assembly, use a vernier caliper to check the outer diameter of the connector jacket after the crimping machine. If it does not match the parameter table, fine-tune the micrometer scale until the next hose crimp meets the requirements. Precautions for crimping machine 1. When crimping, place the joint in the center of the mold as much as possible, and do not press on the hexagonal nut. 2. Prevent tools and other foreign objects from entering the press tube head. 3. Every time after the work is finished, the eight mold bases must be opened to the degree of Z, so that the spring can be in the opened state and the spring can be maintained, and the oil cylinder is also in the pressure relief state to extend the life of the oil seal.

Talking About The Role Of Withholding Machine Cylinder

Talking about the role of withholding machine cylinder The hydraulic cylinder of the crimping machine and the pipe pressing machine is mainly used in places that need to support heavy objects for a long time. It can still support heavy objects when the oil pressure is removed, and it is safe and reliable. It can be used underwater, single-acting, load retraction, and the nut self-locking makes the load safer. Especially in large-scale projects, it is an easy-to-operate control and self-locking jack. It is designed with a safety pressure holding device and a built-in pressure relief valve to prevent overload. To protect the self-locking jack to facilitate safe operation. The user of the crimping machine will feel that the machine is hot during use. In order to make the crimping machine overload and work for a long time, open the crimping machine to dissipate heat. This is a wrong method. Its Z will eventually cause the crimping machine to fail Speed ​​up the damage. How to make the crimping machine better heat dissipation? 1. The user should understand the rules and regulations and safe operation procedures, master the sequence of turning on and off the crimping machine, and understand and master the structural principle of the crimping machine. 2. The dirt in the solenoid valve should be cleaned up in time during use, and the main power supply should be disconnected when maintaining the crimping machine. ? After the operation is over, unplug the power plug, put away the power cord, and clean up the site before the personnel can leave. 3. If the crimping machine becomes hot, reset the foot switch first, and then restart it after shutting down for 2 minutes. Z It is important to have a reasonable heat dissipation area to keep the oil temperature within a reasonable range. Generally, if the crimping machine is overheated, it is necessary to check whether the heat dissipation area of ​​the electrical circuit of the crimping machine is working normally. Servo motors or variable frequency motors often test the surface temperature or noise, and they must be dealt with in time. When the system load changes, simply control the oil to maintain a stable temperature. It is necessary to install a cooling device. Outside dust, sand, etc., friction will also generate heat during the operation of the crimping machine, and the leaking oil flowing back to the oil tank will enter the hydraulic oil. In addition, when repairing, a little carelessness will also cause magazines etc. to enter the hydraulic oil.

Engineering noise reduction solution for hose cutting machine workshop

Engineering noise reduction solution for hose cutting machine workshop Determination of the reverberation time and the noise value of each noise source in the hose cutting machine workshop Reverberation time means that the indoor sound reaches a stable state, and the sound source stops after the sound... Noise reduction engineering solutions for workshops 1. Determining the reverberation time of the hose crimping machine workshop and the noise value of each noise source. Reverberation time means that the indoor sound reaches a stable state. After the sound source stops sounding, the residual sound is reflected back and forth in the room and absorbed by the wall, and the average sound energy density drops to One millionth of the original value (or the time required for the sound energy density to attenuate 60dB). The longer the reverberation time, it means that the sound is reflected multiple times in the workshop, and the energy decay rate is slow. Under the same sound source, the workshop with long reverberation time will have more noise than the workshop with short reverberation time. 2. Selection of sound-absorbing materials Figure 6 shows the basic structure of the sound-proof board. It can be seen from the figure that the sound-proof board is composed of 5 parts. The noise enters the sound-absorbing cotton through the small holes of the perforated board. The energy is converted into heat and consumed, and the other part is isolated by the outer steel plate to achieve the purpose of absorption and sharing. (1) The outer steel plate with a thickness of 2mm plays the role of sound insulation and support, and is the outer surface of the sound-absorbing panel. (2) The middle part of the sound-absorbing board is made of sound-absorbing material, made of glass wool, which is used to absorb sound energy and is the main component of the noise-reducing material. It mainly includes two aspects. On the one hand, the thickness of the outer steel plate, especially in places where low-frequency noise is relatively large, the outer steel plate needs to be thickened, because the sound absorption effect of sound-absorbing cotton on low-frequency noise is far worse than that on high-frequency noise. Absorption; on the other hand, it is the choice of the thickness of the sound-absorbing cotton. Generally, according to the size of the noise, 50-100mm is a commonly used thickness range value. In this noise reduction project, the noise value exceeds the standard more. In order to ensure the noise reduction effect, Make sure that the thickness of the sound-absorbing cotton is 100mm. 3. Lighting treatment Since the interior of the equipment is isolated from the external workshop lighting after the implementation of the enclosed project, a lighting system needs to be added to the enclosed body. In order to ensure the lighting required for production and later equipment maintenance, the design illuminance reaches more than 500 lumens. The lighting system in the enclosed body is individually wired and switched independently to ensure convenient use and does not affect the original power supply system. In addition, in order to prevent sudden power outages in the workshop, an emergency lighting system was installed in the enclosure to ensure the safety of equipment and personnel.

Methods Of Maintenance And Maintenance Of Hose Cutting Machine Equipment

Methods of maintenance and maintenance of hose cutting machine equipment With the continuous development of science and technology, the use of pipe cutting machines has gradually increased. Therefore, the daily maintenance of hose cutting machines has become a concern of everyone. Let’s share with you some daily maintenance of crimping machines. Brief analysis, so that everyone can use it better in the future. 1. The cutting blade of the automatic pipe cutting machine is very close to the clamping system, which can prevent the pipe from vibrating and ensure that it is not deformed. 2. The hose cutting machine has a rigorous structure and is light and easy to carry, which is especially suitable for on-site installation or workshop operations. 3. The cutting is fast, without burrs, and the cutting opening is perpendicular to the axis of the pipe. 4. The hose cutting machine only needs to add an automatic electric revolution control system and a welding power source to realize all-round welding function. 5. The hose cutting machine is suitable for cutting various material pipes. 6. Guide rail cleaning. Guide rails and linear shafts are one of the core components of the equipment. Its function is to play a guiding and supporting role. 7. Fastening motion system of screws and couplings After working for a period of time, the couplings will loosen, and the screws at the moving joints will affect the smoothness of the mechanical movement. Therefore, the transmission parts should be observed during the operation of the pipe cutting machine. If there is any abnormal noise or abnormal phenomenon, it should be strengthened and maintained in time if the problem is found. 8. Cleaning of the lens. 9. Clean the fan. Long-term use of the fan makes the fan generate a lot of noise, which will accumulate a lot of solid dust in the fan, and it is also not conducive to exhaust and deodorization. The crimping machine equipment cannot be left unused for a long time, and can not be used for a long time without shutting down. A reasonable plan for maintenance and maintenance can not only improve the sawing effect, but also extend the service life of the saw blade.
